Abstract (en)

[origin: WO03068846A1] The invention relates to a method for modifying a surface of injection-moulded, extruded or pressed polymeric substrates comprising silicone rubbers. The method comprises the steps of removing and/or ex­tracting liquid low molecular weight residues partly or totally from the substrate, and subjecting the substrate to a surface treatment, e.g. flame, corona, and plasma-treatment. An excellent activation of the surface is achieved.
